73) X Marks the Spot*

Supplies
* masking tape
* blindfold

Goal
To determine who's telling the truth, and thus, to find the "x" on the ground

How to Play
Have everyone form a large circle. Blindfold one player, who will be the "seeker." Now mark an "x" with tape somewhere within the circle. Each of the rest of the players must choose at this point, whether they want to help, or to lead astray, the seeker. They should not say what their choice is, but they should keep to it for the round. The players then shout out directions: "left", "right", "forward", "You're on it", "You're far away", etc.
The seeker's goal is then to move around the circle, trying to find the "x" on the ground (by relying on directions, rather than using hands). Once the seeker thinks he/she is standing on it (or as close as he/she's going to get), he/she says, "I found it!"
Mark the spot where the seeker is standing. After everyone plays, whoever comes closest, wins.

Strategy
The players will be trying to guess based on whether they think their friends would trick or help them, and based on how believable the various voices are.
